CVE-2022-41583 is an array out-of-bounds read vulnerability identified in the storage maintenance and debugging module of Huawei's HarmonyOS version 2.0. This vulnerability arises when the software attempts to read data beyond the allocated bounds of an array, leading to incorrect statistics being generated by the affected module. The flaw is classified under CWE-125, which pertains to improper bounds checking. The vulnerability has a CVSS v3.1 base score of 7.5, indicating a high severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N) reveals that the vulnerability can be exploited remotely over the network without requiring any privileges or user interaction. While the confidentiality and availability impacts are rated as none, the integrity impact is high, meaning that the vulnerability can cause incorrect or manipulated data outputs from the storage maintenance module. Although no known exploits have been reported in the wild, the potential for attackers to leverage this vulnerability to disrupt the integrity of system statistics or diagnostics is significant. The absence of a patch link suggests that remediation may still be pending or not publicly disclosed. Given that the vulnerability affects HarmonyOS 2.0, which is Huawei's proprietary operating system primarily used in IoT devices, smartphones, and other smart devices, the scope of affected systems includes any device running this OS version with the vulnerable module enabled.

For European organizations, the impact of CVE-2022-41583 depends largely on the deployment of Huawei HarmonyOS devices within their infrastructure. Enterprises or service providers using Huawei smart devices or IoT equipment running HarmonyOS 2.0 could face risks related to the integrity of storage maintenance and debugging data. This could lead to inaccurate system diagnostics, potentially masking underlying issues or causing misinformed operational decisions. In critical environments such as industrial control systems, telecommunications, or smart city infrastructure where Huawei devices might be integrated, this could degrade trust in system health monitoring and complicate incident response. Although the vulnerability does not directly compromise confidentiality or availability, the high integrity impact could facilitate further exploitation or persistent misconfigurations if attackers manipulate diagnostic outputs. The lack of required privileges or user interaction for exploitation increases the risk profile, especially for network-exposed devices. However, the absence of known active exploits somewhat reduces immediate threat levels. Overall, European organizations relying on Huawei HarmonyOS devices should consider this vulnerability a significant risk to device reliability and operational integrity.

To mitigate CVE-2022-41583, European organizations should first inventory all Huawei devices running HarmonyOS 2.0 within their environment, focusing on those with storage maintenance and debugging modules enabled. Since no public patch is currently linked, organizations should engage with Huawei support channels to obtain any available security updates or advisories. Network segmentation and strict access controls should be implemented to limit exposure of vulnerable devices to untrusted networks, reducing the attack surface. Monitoring and anomaly detection should be enhanced around device diagnostics and maintenance data to identify irregularities that may indicate exploitation attempts. Where feasible, disabling or restricting access to the storage maintenance and debugging module can reduce risk. Additionally, organizations should consider deploying endpoint detection and response (EDR) solutions capable of identifying abnormal read operations or memory access patterns indicative of out-of-bounds reads. Finally, maintaining up-to-date asset inventories and applying a risk-based approach to device usage can help prioritize remediation efforts until official patches are available.
